In this book the authors present several examples of techniques used to overcome the Abby diffraction limit using flat and 3D diffractive optical elements, photonic crystal lenses, photonic jets, and surface plasmon diffractive optics. The structures discussed can be used in the microwave and THz range and also as scaled models for optical frequencies. Such nano-optical microlenses can be integrated, for example, into existing semiconductor heterostructure platforms for next-generation optoelectronic applications.

Chapter 1 considers flat diffractive lenses and innovative 3D radiating structures including a conical millimeter-wave Fresnel zone plate (FZP) lens proposed for subwavelength focusing. In chapter 2 the subwavelength focusing properties of diffractive photonic crystal lenses are considered and it is shown that at least three different types of photonic crystal lens are possible.

With the aim of achieving subwavelength focusing, in chapter 3 an alternative mechanism to produce photonic jets at Terahertz frequencies (terajets) using 3D dielectric particles of arbitrary size (cuboids) is considered. A scheme to create a 2D "teraknife" using dielectric rods is also discussed. In the final chapter the successful adaptation of free-space 3D binary phase-reversal conical FZPs for operation on surface plasmon-polariton (SPP) waves demonstrates that analogues of Fourier diffractive components can be developed for in-plane SPP 3D optics.

Review ing theory, modelling and experiment, this book will be a valuable resource for students and researchers working on nanophotonics and sub-wavelength focusing and imaging.

In the field of diffractive optics of millimeter/THz wave Professors I.Minin and O.Minin achieved a number of pioneering results. They are the world leading authority on arbitrary 3D diffractive focusing elements. In particular, they for the first time observed 3D subwavelength resolution for diffractive optics with focal distances less wavelength. Profs. Minin introduced 3D real time quasioptical radio vision system for detection of hidden objects in millimeter/THz waves based on frequency properties of 3D diffractive optics and provided the first observations of the real-time images with quality equal to optical.
They discovered and studied the ablation and erosion process on hypervelocity flight of metal body in millimeter wave. Profs. Minin introduce a pulse plasma antenna, including explosive antenna in microwaves/millimeter waves.
Profs. Minin recently started highly innovative work on sub-wavelength light concentration and super-resolution using the concept of arbitrary 3D dielectric particles.
